Description
Gewinnung von Schwefel aus schwefelhaltigen Massen Es ist bekannt, den Schwefel mittels heißen Wassers oder gespannten Dampfes auszuschmelzen. Ferner ist bekannt, diejenigen Schwefelmassen, wie sie beispielsweise bei der Schwefelwasserstoffentfernung anfallen, mit Luft oder Sauerstoff zu regenerieren. Bei dieser Regeneration fällt ein Rohschwefel an, auf dessen Weiterverarbeitung sich die vorliegende Erfindung bezieht, und zwar erstreckt sich die Erfindung auf ein Verfahren zur Gewinnung von Schwefel aus solchen schwefelhaltigen Massen, wie sie bei der Reinigung schwefelhaltiger Gase durch Aufschlämmungen oder Lösungen von Eisenverbindun.gen nach anschließender Regenerierung dieser Flüssigkeiten durch Oxydation erhalten werden. Durch Behandeln einer solchen Masse mit heißem Wasser bei einer Temperatur, die oberhalb des Schmelzpunktes des Schwefels liegt, erhält man folgende getrennt anfallende Stoffe: r. Schwefel von einem Reinheitsgrad von etwa 98 bis 99%, z. eine wäßrige Suspension von Eisenhydroxyd, 3. einen festen Rückstand, der im wesentlichen aus Eisensulfid besteht.Extraction of sulfur from sulphurous masses It is known to melt out the sulfur by means of hot water or pressurized steam. Further is known, those sulfur masses, as they are, for example, in the removal of hydrogen sulfide accumulate to regenerate with air or oxygen. During this regeneration falls a raw sulfur, the further processing of which the present invention is based relates, namely the invention extends to a method for obtaining Sulfur from such sulphurous masses as they are used in the purification of sulphurous substances Gases through slurries or solutions of iron compounds after subsequent Regeneration of these fluids can be obtained by oxidation. By treating such a mass with hot water at a temperature above the melting point of sulfur, the following substances are obtained separately: r. sulfur of a purity of about 98 to 99%, e.g. an aqueous suspension of iron hydroxide, 3. a solid residue consisting essentially of iron sulfide.
Es wurde nun gefunden, daß das Anfallen eines Rückstandes von Eisensulfid dadurch vermieden werden kann, daß gleichzeitig mit dem heißen Wasser auch sauerstoffhaltige Gase, vorzugsweise aber reiner Sauerstoff, zur Einwirkung auf die schwefelhaltige Masse gebracht werden. Das vorliegende Verfahren läßt sich nun in der mannigfachsten Weise praktisch ausführen, sei es, daß man die Masse, die ja bereits Wasser enthält, indirekt, z. B. durch gespannten Wasserdampf, erhitzt und ihr Sauerstoff oder sauerstoffhaltige Gase zuführt, oder sei es, daß man auch heißes Wasser von der angegebenen Temperatur, das demnach also unter einem Druck von 3 bis 5 Atm. steht, auf die Masse zusammen mit Sauerstoff oder sauerstoffhaltigen Gasen zur Einwirkung bringt. Auch eine Kombination dieser beiden Arbeitsweisen ist naturgemäß denkbar. Die bei der Durchführung des beanspruchten Verfahrens angewandte Temperatur kann naturgemäß in weiten Grenzen schwanken. Sie muß aber so hoch liegen, daß sie den Schmelzpunkt des Schwefels erreicht.It has now been found that the formation of a residue of iron sulfide it can be avoided that simultaneously with the hot water also oxygen-containing Gases, but preferably pure oxygen, to act on the sulfur-containing Mass to be brought. The present procedure can now be used in the most varied of ways In a practical way, be it that the mass, which already contains water, indirect, e.g. B. heated by pressurized steam, and their oxygen or oxygen-containing Supplies gases, or be it that one also hot water of the specified temperature, therefore under a pressure of 3 to 5 atm. stands on the crowd together with oxygen or oxygen-containing gases to the effect. Also a combination these two modes of operation are of course conceivable. When performing the claimed process temperature applied can naturally within wide limits vary. But it must be so high that it reaches the melting point of sulfur.
